.A and Apointed ont inthe clainn j In the accompanying-drawings,Fignres 1 and 2 are views illustrating nlyimprovements, -and Fig, 3 is a view of the lock.

A represents an ordinaryraii, and Blishplates disposed on each side thereof between the head and flanges, and'said fish-plates are provided at their lower edgesv with flanges 1, which lextend out overitheiianges of the rail. The sh-plates B. andweb of the rail A are provided with alined holesrforthe passage of 'a bolt C, screw-threadedfat its end for the reception ofthe nutD. A

-My improved nut-lock E is disposed be-V tween the sh-plateB and nut I) and coinrises a metal plate 2, prefegably rectanguar in shape and adapted to rest on the flange and to which preferably corners will sli u the same until' free thereof, when't esp'ring path' of `the side offl the" n'utand pre- Patent, is .Y
